7 SHUTTER OPEN/CLOSE CONTROL
The oscillator output section has a safety provision. It is a shutter
mechanism that can mechanically shut off the laser beam output as
required. To output the laser beam, it is necessary to open the shutter
previously.
There are two methods for opening the shutter automatically, as
described below.
Which method to use can be selected using parameters.
(1) Command using the G code
In automatic operation mode, specifying G32P-; or G32L-; opens
or closes the shutter.
• If P≠0 or L≠0, the shutter is opened.
• If P=0 or L=0, the shutter is closed.
(2) Command using the PMC signal
The shutter open signal from the PMC can be used to open or
close the shutter. This method may be selected when you want to
control the shutter using the M code or from the outside.
• Turning on the shutter open signal opens the shutter.
• Turning off the shutter open signal closes the shutter.
Another safety provision is available. It is a shutter lock signal used to
disable the shutter from opening. When the shutter lock signal is on, it
nullifies the shutter open command, thereby keeping the shutter
closed.
